Desalination With Small Electrical Fields — Simple New Method May Revolutionize Seawater Desalination

The new method — electrochemically mediated seawater desalination — uses no membranes, is considerably simpler than conventional methods, and is so low-energy that it can be performed with the energy provided by store-bought batteries. Those are big improvements on all fronts — if the process can be adequately scaled-up it’s a potentially revolutionary development. Freshwater scarcity is expected to become a significant problem in many regions of the world in the coming decades, but as it stands now, saltwater desalination isn’t particularly economical… A cheaper, simpler method than those currently available would be of great use — one which could be used on larger scales than simple
